The power outage time caused by a broken transformer varies depending on the type and damage situation of the transformer.
For small transformers, they are commonly used in residential areas and urban roads, with a capacity typically below several hundred kilovolt amperes. Due to their generally circular construction, maintenance is more convenient. Therefore, when a malfunction occurs, the power outage time is usually not too long, usually between 1 to 2 hours. Maintenance personnel can inspect, repair, and replace components of the transformer on site, generally without the need to disassemble the transformer.
Large transformers are generally used in power systems, with a capacity of several hundred kilovolt amperes or more. These transformers usually adopt a layered structure, making maintenance difficult. When a malfunction occurs, the repair time may be longer. Common faults of large transformers include winding breakage, insulation breakdown, oil leakage, and cooling system failure, all of which require disassembly for maintenance. Therefore, the maintenance of large transformers requires a longer time, and the power outage time will also be correspondingly extended.
Please note that the specific power outage time also depends on factors such as the specific cause of the malfunction, the complexity of maintenance work, the availability of maintenance personnel, and the availability of spare parts. When a transformer malfunctions, it is usually necessary to apply for a shutdown to the relevant department and record the specific shutdown time and power restoration time for subsequent review and calculation of shutdown days.
In addition, the power supply company will also notify users in advance of the power outage time based on the planned or temporary maintenance needs of the power supply facilities. When power outages or restrictions are required due to faults in the power generation or supply system, the power supply company will also carry out power outages or restrictions in accordance with the predetermined order of power restrictions.
Overall, the power outage time caused by a broken transformer is a relatively complex issue that requires comprehensive consideration of multiple factors. To ensure the reliability and stability of power supply, it is recommended to regularly maintain and inspect transformers to promptly identify and address potential issues.
